How Red & NIR Light Therapy Works
The IRW-004 utilizes specific, scientifically validated wavelengths of light to work at a cellular level via Photobiomodulation (PBM), supporting the body’s natural processes non-invasively.

  • 660nm Red Light: Primarily absorbed by skin layers, helping to promote collagen production, improve surface skin conditions, and aid wound healing.
  • 850nm Near-Infrared (NIR) Light: Penetrates deeper into tissues, helping reduce inflammation, alleviate deeper muscle and joint discomfort, accelerate recovery, and enhance cellular energy (ATP).

By delivering both wavelengths at a high intensity of >150 mW/cm², the IRW-004 provides focused and efficient therapeutic benefits to the targeted area.
